MIAA-555 Luna Tsukino got an erection when she saw her childhood friend who was helping me being raped by a bully.

Luna is my childhood friend who has always helped me when I was bullied. - He came to help me today too! - But this time, the other person was at fault... He took my place and became lewd! - Now it's my turn to muster up the courage and help! - Um... I... have an erection. - Even though my precious benefactor is being fucked. - ...I want to see more, cry more. - Ah...how awesome. - I can't believe I get to see my beloved Luna like this... - I just realized...I like the way you get raped lol, my benefactor NTR! - Scum erection!
